Japanese Patent No. 3413804

However, the above-described conventional discharge container has a problem that dust and dirt are easily clogged in the vent hole of the overcap because the vent hole is formed in the peripheral wall portion and the top wall portion of the overcap. If dust or the like is clogged in this way, the overcap not only becomes unsanitary, but also the flow of outside air into the overcap is hindered, and the air permeability of the overcap is reduced. As a result, the surface of the nozzle cylinder becomes difficult to dry, and there arises a problem that germs easily propagate on the surface of the nozzle cylinder.
Further, the conventional discharge container described above has a problem that dust and the like easily adhere to the nozzle cylinder because dust and the like easily enter the overcap through the vent of the overcap.

  The present invention has been made in consideration of the above-described conventional problems, and an object of the present invention is to provide a discharge container capable of maintaining an overcap and a nozzle cylinder in a good sanitary state.

A discharge container according to the present invention includes a container body that contains contents, a nozzle cylinder that is disposed above a mouth portion of the container body and that is provided with a discharge port that discharges the contents, and the mouth An overcap that is detachably attached to the portion and accommodates the nozzle cylinder inside, and a concave groove that extends upward from a lower end of the overcap on an inner peripheral surface of the overcap And a recess that is open to the outside and communicated with the groove is formed in the shoulder of the container body .

  With such a feature, since the outside air flows into the overcap through the recessed groove, the air permeability inside the overcap is improved. Moreover, since the above-mentioned concave groove is formed on the inner peripheral surface of the overcap and is opened at the lower end of the overcap, and the inside and outside of the overcap communicate with each other through this concave groove, the concave groove is the overcap. Since it is opened at the lower end of the groove, dust or the like is unlikely to enter the overcap through the concave groove, and dust and dirt are not easily clogged in the concave groove.

The shoulder of the container body is open to the outside and has a recess communicated with the groove, so that the lower end of the groove is less likely to be blocked, and the outside air passes through the groove. It becomes easy to flow into the cap. That is, outside air flows into the concave groove from the lower end of the concave groove through the concave portion of the shoulder portion of the container body, and flows into the overcap through the concave groove.

  Further, in the discharge container according to the present invention, the discharge port is disposed on an upper end surface of the nozzle cylinder, and a seal convex portion that closes the discharge port protrudes on a lower surface of the top wall portion of the overcap. It is preferable to be provided.

  Thereby, since the discharge port is closed by the seal convex portion, the contents are prevented from leaking from the discharge port, and the discharge port is difficult to dry.

According to the discharge container of the present invention, the outside air flows into the overcap through the concave groove, and the air permeability inside the overcap is improved, so that the surface of the nozzle cylinder is easily dried. As a result, it is difficult for germs to propagate on the surface of the nozzle cylinder, and the nozzle cylinder can be maintained in good sanitary condition.
In addition, since dust and the like are difficult to enter through the concave groove, it is possible to prevent dust and the like from adhering to the surface of the nozzle cylinder, and the nozzle cylinder can be maintained in a good sanitary state.
In addition, dust and dirt are not easily clogged in the ditch, and even if dust is clogged in the ditch, it can be easily removed, so the overcap can be maintained in good hygiene, The air permeability inside the overcap can be reliably maintained, and the nozzle cylinder can be maintained in a good sanitary condition.
